Auxiliary Markers

Color bands are used as auxiliary markers to aid in identifying individual birds. We offer Darvic, Celluloid, and Acetal color bands to suit your research need. Darvic is the trade name for unplasticized PVC, and is dyed with colorfast dyes and is UV resistant. Celluloid bands are a thermoplastic band type that have limited availability, as much of the sheet material required to make the bands is disappearing. Acetal bands are a type of acetate band that are molded on to a small card or stick, off of which individual bands are snapped off for use. For use in the US and Canada, permits are required unless for captive use.
